Here is what you can do. you need to convert the copy protected itunes music to something not copy protected and in the proper download format for the car. I know wav works. Copy to a CD or USB and download.

I use a tool called: tuneclone to unprotect the itunes music. It works by simulating a burn to a cd-rom and then storing on your computer. I output in 128 bit MP3 as it's good enough for the car with all the ambient noise.

Then copy the music to a USB or burn CD-ROM's from the images and go download.

Tuneclone can be found at: www.tuneclone.com

Have fun.

P.S. I wish the harddrives were bigger. I use a 3 gig USB and leave it in most times now.
